Application led August 19, 1912. Serial N o. 715,928.

To all whom it may concern:A Be it known that I, ANDR TnIoU, engineer, a citizen of the French Republ1c, residing in Henri-Littolf aux Vallees, Seine, France, have invented certain new and useful 'Improvements in Lockin'g'Devices for Grease-Cups, of whichthe following is a specification.

The present inyentionhas reference to' grease cups and the like,

which is actuated through the direct agencyy of the cap, to--hold the latter in adjusted position, and which has associated with it certain adjuncts that serve to release the clutch action of the ball.

The accompanying drawing shows averwith the improved locking device.

In said drawing, the part to whichithe grease cup is attached is indicated by the letter' A, irrespective of the"character of such part, since the invention i's'concerned only with the device associated with the grease cup.

,The grease cup may be of any desired type, but it is to be understood thatno limitation to the type shown, nor, in fact, to a 'grease cup itself. is contemplated, for the reason that the invention is applicable to any article of an analogous nature comprising a body, and a cap adjustably carried thereby, these parts being indicated7 respectively, by the letters t and Referring more particularly to the draW- ing, the cap Z)- is slidably fitted upon the body c and is .itself encircled, in turn, by a slidable sleeve-like element t'. The balls (Z are carried in flanged openings in the lower portion of the ca '5 and trictionally engage the outer surface or wall' of body a'. The sleeve c is held in raised position by an er;q pansible spring e, and is formed with an inturned bottom portion o0 with which the balls i also coast, this portion '0 constitutthe female member of the clutch. De-

briedy, an improved device? grease cup equipped y pression of sleeve c will c ii'ect unshipping of the clutch.

v,To prevent accidental disengagement of the body a, the latter is formed with a circurnferential groove d which serves to give audible notice of the cap' reaching the position where the clutch action begins to take place, since a' slight click ,is heard when the balls pass over the groove;

I claim as my invent1on:- 'l 1. In a devic'eof the class specified, the combinatlon of a body part; an adjustable cap encirclingsaid body and slidable endi wise thereon .a series of clutch elements carried by said cap; and an annular member encircling said cap and slidable endwise l -thereon for forcing said clutch elements into binding engagement with said body to hold the cap in adjusted position thereon.-

2. In a device of the combination of a hollow, lindrical container g' an ably open-topped. cyadjustable cap slidencircling said container and covering the top thereof; a series of clutch elements carried by, said `cap; and an annular memberslidably encircling said cap for forcing said clutch elements into binding engagement' with said container, to hold the cap .in adjusted posit-ionlthereon.

In a device of the: class specied, the combination of a body part; an adjustable cap encircling said body and slidable endwise thereon ;4 a series of clutch elements carried by said cap; an annular member encircling said cap and slidable endwise thereon for forcing saidclutch elements into binding engagement cap in adjusted position thereon; and means or normally holding said member in operative position.

class specified, the

with said body to hold the 4. In a device of the class specified, the

combination of a body part; a cap encircling said body and slidable endwise thereon in opposite directions, said cap belng formed with a series of seats: a series of clutch elements mounted in said seats and movable into and out of binding engagement with said body to hold said cap 1n adjusted position thereon; and an annular member encircling said c ap and slidable endwise thereon in opposite directlons, said member having an in-turned portion cooperative with said clutch elements for forcing-the same into, or releasing them from, such engagement.

5. In adevice of the class speclfied, the

combination of a bod part; a cap encircling said body and slidable endwise there- .on in opposite directions, said cap being formed with a series of seats; -a series of clutch elements mounted in'said seats and movable into and out of binding engagement with said body to hold said cap in adjusted position' thereon; an annular member encircling said cap and slidable endwise thereon in opposite directions, said mel er having an iii-turned portion copera ive with said clutch elements for forcing'the same into, or releasing them from, such 'ngagement; andmeans for normally holding said member in position to effect suoli engagement. f

6. In a device of the class specified, the combination of a body part; a cap encircling said body and slidable endwise thereon in opposite directions, said cap being formed with a series of seats; a series of clutch elements mounted in said seats and movable into and out of binding engagement with said body to hold said cap in adjusted position thereon; an annular member encircling said cap and slidable endwise thereon in opposite directions, said Amember having an n-turned portion co* operative with said clutch elements for forcing the same into, or releasing them from, such engagement; and a spring interposed between said cap and said member and acting against the latter, to normally hold it in position to effect such engagement.

7. In a device of the class specified, the combination. of a body part: an adjustable cap encircling said body and slidable endwise thereony; al series of clutch elements carried by s id cap; an annular member encircling sa'd cap and slidable endvvise thereon fyir forcing said clutch elements into bind'ng engagement with said body to hold the cap in adjusted position thereon; and a/spring interposed between said cap and said member and acting against the latter, to normally hold it in operative po-l sition.

In testimony whereof I have hereunto set my hand in presence of two 4subscribing Witnesses. A A ANDR TRIOU.
